The following is a dehydration synthesis reaction. which of the following correctly fills in the missing molecules? c6h12o6 + c6h12o6 --> +
a. c6h12o6 + c12h22o11
b. h2o + c12h24o12
c. cannot determine
d. c12h12 + h12o12
e. h2o + c12h22o11

option E= H2O + C12H22O11

Explanation:

Dehydration synthesis:

It is the chemical reaction i which two molecules combine to gather to form new compound with the removal of water.

For example two glucose molecules combine to gather to form one maltose and water molecule.

Chemical equation:

C6H12O6 + C6H12O6 → C12H22O11 + H2O

one glucose molecule gives OH- ion while other give H+ to form water molecule.

Most of biological molecules like nucleotides, triglycerides, carbohydrates and proteins are also formed through this reaction.

In dehydration synthesis monomers are combine go form the polymer through the covalent bond.

Key points:

1. During dehydration process hydroxyl group of one monomer combine with the hydrogen atom of another monomer to form the polymer

2. The two hydrogen from one monomer and one oxygen atom from other monomer can also be combine to form water molecule.

3. These monomers joined together through covalent bond by sharing of electrons.

4. The additional monomers can also join and multiple dehydration process occur, monomers repeat, long chain is formed i,e polymer molecule.

Monomers of glucose molecules can join in different way and form variety of molecules. The amino acids and nucleotides are also combine together to form variety of compound through different sequences.
